Here is the recipe for making play-doh. Recipe #1 is my favourite. It stays soft and pliable. It is easy to wash and comes with no plastic container from the store. I have been making this play-doh for over 2 years. It is 100% better and does not have such a strong odor as the store bought.
Jack was my helper for most of the play-doh making. He was super excited! First we made the raspberry dye play-doh. The colour came out a very light pink. Could have used more juice for a darker colour. I would say we used about a tsp worth. I will add, my camera on my tablet is not so well. The colour is much better in person compared to the pictures.
Next came the blueberry dye. This one turned out a light purple. It could also use a larger amount of juice for the dye. I would say I used about 2 tsp. I did not measure.
Next came the coffee dye. Yes the play-doh smells like coffee! just slightly though, and the kids do not eat the play-doh. That has never been a problem. Maybe a lick here and there when pretending to make ice cream. lol. Nothing for me to worry about, really. So instead of using 1 cup of water to start, I used 1/2 a cup of water and 1/2 a cup of coffee for the dye. The colour turned out a light tan. I could have probably boiled off more water from the coffee, but I was experimenting and tried just a small brew to concentrate it that way.
Next came the turmeric. I added a 1/2 tsp to start, but the colour was the same as the coffee, or very close. I added another 1/2 tsp, and there was not a whole lot difference. So I took some mustard powder, 1/2 tsp worth and it brightened the colour a little. by the time I had the yellow I was looking for, I used 2 tsp of turmeric and 2 tsp of mustard powder. This one is my favourite. It came out bright.
Last came plain old white. No dye is needed for this one.
For this process, I was using two pots, a whisk and a silicone scraper. As one play-doh was finished cooking, the used pot was set aside to cool. A new pot was put on the stove with ingredients added. No heat turned on yet. The cooled pot was put in an empty sink and filled with water to loosen the dried/baked on play-doh. That would soak until the new batch of play-doh was ready, which the hot pot would be set to the side to cool and the pot in the sink ready for a wash out, dry and use. The cooled pot would get a soak and repeat until finished. The utensils would get a quick rinse in between so colours would not mix.
I am hoping the natural dyes will stay well with the play-doh. Chris was wondering if the dyes would stain clothing. After handling the play-doh myself (kneading), there was not stain on my hands. So I think it will be fine. I still have store bought dyes to use up as well.
Jack was asking if I could make blue play-doh. I don’t know off hand what to use to make blue dye naturally. I ran out of cream of tartar as well, so next time blue play-doh for Jack.
I would like to find natural dyes for Red, Blue, Green, Orange and Black.
Beet juice is on my list. I want to find natural dyes without packaging as much as possible.
Raspberries = light pink (need more than a tsp)
Blueberries = purple (need more than 2 tsp)
Turmeric and mustard powder = yellow (Great with 2 tsp each)
Coffee = tan (need a more concentrated coffee)
